We loved Hotel Ariston. Decor is modern and very comfortable. The bed was very comfortable. We were in room 23 on top (3rd) floor with view of the lake, which I recommend. Our room looked directly out onto the tower and the view was fantastic. Breakfast was good, especially outside on the patio or in the relaxing garden.
The staff was incredibly warm and welcoming and helped us every day. Renatta at the desk answered all of our questions, and went out of her way to help us. We wanted to golf one day, very impromptu, and she called the place to ensure that we could get on. The course didn't answer, so she called back. Again, and again, and again until she got them and heard that they had a spot for us. It was a delight speaking with her and all the staff there.
I needed an iron one morning and asked a maid that was in hallway. She didn't speak English and my Italian is not very good either. We laughed at each other pointing and gesturing and finally figured it out. She walked me down to the basement and showed me what I needed.
The Italian people in general are warm and friendly. The staff at Hotel Ariston are great representatives of this. We felt welcome there from minute one.
The only suggestion I'd make is to improve the wifi signal on the upper floors. We found that we needed to do internet in the lobby, which was fine by us. We took care of this in the morning at breakfast before heading out for the day.
